JOHN-L. BOGERT, OF FLUSHING, NEW YORK.

DEVICE FOR RECIPROCATINGTHE CUTTER-HEADS 0F PLANING AND SLOTTING MACHlNl-IS.'

SPECIFICATION forming part of Letters Patent.No. 278,084, dated May 22, 1883. Application filed February 23, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN L. Boomer, of Flushing, in the county of Queens and State of New York, have invented an Improved Mechanical Movement; for Actuating Gutter- &c., of which the following is a specification.

The object of this invention is to give a fast movement in one direction and a slow movement in the other direction, and to vary the length of the stroke or movement at will with This movement is especially adapted to slotting and metal-planing machines, wherein the work is done by the movement in one direction, which requires to be steady and" comparatively slow, and the return movement may be rapid, because the tool or cutter is not in action, and, furthermore, the length of out can be varied without stopping the machine, thus effecting a great saving of time and enabling the workmen to do better work.

In the drawings, Figure 1 is a sectional elevation, and Fig. 2 is a side view, of the mechanical movement as applied to a metal-slotting machine. Fig. 3 is a section at the line as m. Fig. 4. is a diagram illustrating the movement given to the slotted lever. The frame a, bed I) for the article to be slotted or planed, the sliding stock 0, tool-holder d, and tool 0 are to be of any desired character, and the slotting or planing tool may operate vertically or horizontally, these two forms of machines being well known.

My improvement relates to the means made use of to give the fast and slow movements, aforesaid to the tool.

The double-slotted lever F is provided with a' pivot shaft or stud, 9, that passes into the frame of the machine or into a hearing or journal-box, and on which shaft as a pivot the slotted lever rocks.. The .slot passes across the end of the stud 9, such slotted portion h of the lever F being made with or permanently connected to the pivot-shaft g. The block is is adapted to slide in the slot h, and it is moved back and forth by the screw 'i and handle I, the screw being held by bearin gs near its ends, so that it cannot move endwise; but the screw is free to be rotated by its handle. Although the slotted lever F swings upon its pivot-shaft g, the handle l can be easily operated while the parts are in motion, because said handle is near to the pivot-shaft and receives butlittle swinging movement. Upon the block is there is a stnd'or hinge connection, 0', for the link p, that at its other end isconnected to the tool stock or slide 0. The "lever F has a second slot, 8, that preferably is parallel with the slot h; but it may be oblique to the same, and in this the block 0' slides by the action of the crank-pin t, the slots being of sufficient length to allow the crank-pin to move the block r back and forth in the slot as the crank revolves and swings in the lever.

It will be seen by the diagram Fig. at that the relative positions of the crank-shaft and its crank to the pivot g are such that the crank tmoves abouttwo-thirds of its revolution while the lever F is swinging in one direction, and that the crank-pin it gives the return motion in the other direction in about one-third ofits revolution.

The connecting-rod and parts are arranged so that the slow motion is in the proper direction, and the fast motion is during the return-stroke, while the cutter is out of action.

By adjusting the position of the block 70 by the screw i the same is brought nearer to or farther from the pivot-shaft g, and the length of motion given to the cutter will thereby be varied, and when the block is central or in line with the pivot-shaftg the cutter will not receive any motion.'

.The shaft o and its crank-pin t may be revolved by an y con venientmeans. .Ihave shown the crank-pin t as upon the gear-wheel u, and

a pinion, w, and shaft to as the means for actn ating the said shaft and crank.

I claim as my invention-- 1. The lever F, having the stud or shaft 9 as its pivot, and the slot 7i, crossing at the end of thepivot g, and the second slot, 8, in

combination with the crank-pin t, and its block sliding in the slot 8 and giving a swinging movement to thelever, and the block 70 and screwi in the slot h,an(l a connecting-rod from screw 1' to adjust the position of the same, sub- I0 the block 70 to the article to be moved, substantially as set forth. stantially as set forth. Signed by me this 3d (lay of February, A.

2. In combination with the sliding cutter- D. 1883. 5 stock and cutter in a metal planing or slotting machine, the lever F, having the pivot-shaft g, JOHN BOGERT' the two slots h and s, the crank-pin and block Witnesses: to swing the lever, the connecting-rod to the GEO. T. PINOKNEY,

cutter-stock, the block 7c in the slot h, and the WILLIAM G. MOT'I.
